Kind of off topic but it always bugs me when I see people using 'average' as a metric. Average is awful, it is a lossy metric that doesn't capture distribution. What if there are only very big books (600+ pages) and very small books (100 pages), we can end up with an average of 325 pages which is actually not any book.
